Green Book star Frank Vallelonga Jr Jr. has been found dead outside a building in the Bronx, New York.
Authorities have since confirmed that a man has been arrested in relation to his death, per PEOPLE.
Vallelonga, 60, is best known for his role as Rudy Vallelonga in the 2018 film Green Book appearing opposite Viggo Mortensen and Mahershala Ali.
In a news release obtained by PEOPLE, the body of the actor was found outside a building, with the New York Police Department not yet releasing the cause of death.
Police were informed of "an unconscious male" in the Bronx around 3:50AM local time on Monday. Per the release, the actor was found "unconscious and unresponsive, on the ground at the location.
"The male had no obvious signs of trauma observed. EMS responded to the location and pronounced the male deceased at the scene," the statement added.
According to the New York Post, the body was outside a sheet-metal manufacturing factory about being thrown out of a car.
Sources told The Post at the time that the actor had allegedly passed away due to a drug overdose. The NYPD told The Post that surveillance footage had captured the late actor being pushed out of the car.
Police have arrested 35-year-old Stephen Smith, who was allegedly the driver of the car during the night in question.
Smith has been charged with concealment of a human corpse, per the release obtained by PEOPLE. He has since denied any involvement with the actor's death, allegedly claiming: "That dude was dead already."
Vallelonga came from a family of celebrities, with his father being actor Tony Lip, who famously starred in The Sopranos, Donnie Brasco, The Goodfellas, and The Godfather, per Variety.
Born Frank Vallelonga, he was the real-life figure that Viggo Mortensen portrayed in Green Book. The actor passed away in 2013 aged 82.
The investigation into Frank Vallelonga Jr's death is currently ongoing, with the medical examiner looking into the exact cause of death.
Green Book was nominated for two Academy Awards and won two for Best Picture and Best Original Screenplay, but came under fire from critics for "its depictions of race and biographical elements about Shirley."
